Is it representative of the notion that if you theorise enough, you will eventually get that spark that will allow you to view things more clearly? It could be just a drawing- That's my theory. Incidentally, last Sunday i heard for the fisrt time in my life 'Desert Island Discs'. Well, i listened to the first 5 minutes, I did'nt get his name, it was a nobel prize-winning scientist. Ain't scientists big-headed though!!
